Jhon The Ripper

John the Ripper is free and Open Source software, distributed primarily in source code form. If you would rather use a commercial product tailored for your specific operating system, please consider John the Ripper Pro, which is distributed primarily in the form of “native” packages for the target operating systems and in general is meant to be easier to install and use while delivering optimal performance.

Proceed to John the Ripper Pro homepage for your OS:

• John the Ripper 1.7.3 Pro for Linux
• John the Ripper 1.7.2 Pro for Mac OS X (also included is a beta version of 1.7.3.1 Pro)

Download one of the latest free “development” versions:

• John the Ripper 1.7.3.1 (Unix - sources, tar.gz, 796 KB) and its signature
• John the Ripper 1.7.3.1 (Unix - sources, tar.bz2, 642 KB) and its signature
• John the Ripper 1.7.2 (Unix - sources, tar.gz, 790 KB) and its signature
• John the Ripper 1.7.2 (Unix - sources, tar.bz2, 675 KB) and its signature

or the latest free “stable” release:

• John the Ripper 1.7.0.2 (Unix - sources, tar.gz, 784 KB) and its signature
• John the Ripper 1.7.0.2 (Unix - sources, tar.bz2, 675 KB) and its signature
• John the Ripper 1.7.0.1 (Windows - binaries, ZIP, 1360 KB) and its signature
• John the Ripper 1.7.0.1 (DOS - binaries, ZIP, 895 KB) and its signature

Note: a few Windows “antivirus” and “anti-spyware” products have started to recognize password recovery tools as if they were “trojans”. This is how those products’ vendors inflate their detected “virus” counts. The effect is that end-users are no longer able to check password recovery software for real viruses. If this affects you, please complain to your antivirus vendor.

Please refer to these pages on how to extract John the Ripper source code from the tar.gz and tar.bz2 archives and how to build (compile) it.

The only change between 1.7.0.1 and 1.7.0.2 is irrelevant for 32-bit platforms, hence there are no builds of 1.7.0.2 for Windows and DOS (they would have been exactly the same as those of 1.7.0.1).

In practice, 1.7.2 (a “development” version) has been around for a long time now, and it has been found to be at least as stable as 1.7.0.2, so the use of 1.7.2 is recommended.
